ili još zdravija i ukusnija varijanta:

Recept

U prazan zagrejan tiganj ubaciti nasečene šampinjone, svakog minuta ih promešati tako da svaki od njih svakom stranom dotakne dno tiganja. Peći bez vode i ikakvih dodataka oko 3 minuta, zatim dodati seckan crni luk, crvenu papriku, seckan beli luk i dinstati još 3 minuta. Zatim sipati jogurt i prstohvat origana, promešati još 1 minut. Možete na kraju dodati ocedjene sardine iz konzerve ili tunjevinu i usitniti ih pri mešanju u tiganju, obavezno pobiberiti, a alevu papriku možete dodati po ukusu na vrh kašičice.

Ovo jelo jedite bez hleba, krompira i ikakvih ugljenih hidrata, ulje, puter, masnoća nije potrebna.

Možete jelo služiti uz neku salatu od krastavaca i paradajza.

Ova snažna mješavina posebno je efikasna za snižavanje holesterola i visokog krvnog pritiska.

Sastojci

– 1 ribani češnjak
– 1 kašika soka od limuna
– 1 komad naribanog đumbira
– 1 kašika jabučnog octa
– 1 kašika organskog meda
Priprema

Priprema je vrlo jednostavna – samo pomiješati sve sastojke i staviti smjesu u frižider na 5 dana.

Kako se koristi:

Nakon pet dana, uzmite smjesu prije doručka i večere, ali nikad više od tri puta dnevno. U samo sedam dana, osjetit ćete rezultate – napravite test krvi i vidjet ćete da je vaša razina holesterola niska. Vaš krvni pritisak također će se normalizirati.

Odmah uvedite radikalne promene u jelovnik, a ne postepene. Zaboravite na šećer i ugljene hidrate. Jedite sveže povrće, ali ne i krompir. Jedite malo voća (bobičasto najviše), orašaste plodove i semenke, posno meso, domaća jaja i maslinovo ulje. Faza traje dve nedelje.

Doručak: kajgana od dva jajeta sa crnim lukom, paprikama, keljom, povrćem i zelenim čajem.

Ručak: Garden salata i jabuka.

Užina: humus sa celerom ili šaka orašastih plodova.

Večera: Grilovano belo meso sa brokolijem na pari, sa paprikom i salatom od svežeg povrća.

Font settings in Thunderbird are a little tricky

Font settings in Thunderbird are a little tricky. These settings work for me.

1) main menu bar

  View > Character Encoding > Auto-Detect > set to "Universal"

2) View > Message Body as > set to "plain text"

3) Tools > Options > Display > Formatting > set preferred default fonts and sizes

4) Tools > Options > Display > Formatting > Advanced

a) Western Page

set fonts and sizes as desired

tick "Allow messages to use other fonts"

tick "Use fixed width font for plain text messages"

Outgoing Mail UTF-8

	   Incoming Mail UTF-8

untick "When possible use the default character encoding in replies"

b) On "Fonts For" drop-down menu repeat the procedure for Unicode and Central European.

c) On "Fonts For" drop-down menu select "User Defined" and repeat the procedure.

This will cover most messages, but you may have to repeat this for any other character encodings that cause you problems. For example, messages in ISO 8859-7 will mean you have to change the "Greek" page too. If you don't know which character sets correspond to the Thunderbird pages they're all on Wikipedia and elsewhere.

5) Go to Tools > Options > Advanced > Config Editor

mailnews.force_charset_override false

6) Folder Properties

Default Character Encoding User Defined

Uncheck 'Apply default to all messages'.
